Reply to comment by needtofigureshitout in Study Suggests Wild Blueberries Help Burn Fat. Results showed participants burned notably more fat after consuming wild blueberries. For example, fat oxidation rate rose by 19.7%, 43.2%, and 31.1% at 20, 30, and 40 min after cycling. by Wagamaga

Pre-workout as in the supplement powder not as a reference to timing. Basically to compare it to other supplements.

And per my understanding they fasted overnight for a morning workout. I’m interested in the timing between ingestion and beginning the work. Does the benefit decrease with increasing time and if so how much - is 12, 8 or even 2 hours enough to see a noticeable decrease in effectiveness?

"Or if eating anything healthy before a workout"

I understood that as you meaning that they had the blueberries before working out. The study was meant to evaluate anthocyanin content in the diet having an effect, i don't think they were considering timing. But that would be interesting to see. EGCG shows increased fat oxidation when taken prior to exercise.

Ah I see where I wasn’t clear. That’s my bad. To clarify, I was wondering what the results would be if they added controls.

Something like: Group 1: 0 supplements + healthy diet + 12 hr fast

Group 2: pre-workout + healthy diet + 12 hr fast

Group 3: blueberries + healthy diet + 12 hr fast

Group 4-n: (same as 1-3 but vary fasting time and dosage to establish max/min recommendations).

I took a look back at some of the reference papers and there’s been several studies already on this particular supplement. I wouldn’t be surprised if someone else has already looked into my questions and I just haven’t come across it yet.

That would be interesting to see. It really is amazing how much stuff is already out there, sometimes I'll randomly think of an effect a food may have on a condition or body function and after looking it up there's already a dozen experiments regarding it.
